PATENT yOFFICE WILLIAM W. LASKEB, OF BROOKLYN, AND HAROLD R. RUSSELL, OF DOUGLASTON, NEW YORK, ASSIGNOBS, BY MESNE ASSIGNMENTS, TO REMINGTON RAND INC., OF NEW YORK, N. Y., A 4CORPORATION OF DELAWARE AUTOMATIC surnomme ma Application med September 17, 1926. Serial No. 136,075.

The present invention relates to card perforating mechanism for record cards, and

4more particularly to an automatic control for selective punch operation.

Some of the objects of the present inventio.. a.; to providel a control for a card perforating machine through the operation of a typewriter, a "bookkeeping machine, an adding machine, or any other separately functioning machine; to provide an automatically selective means for causing only certain predetermined columns of typewritten matter to be perforated on a record card; to provide means for periodically and automatically preventing and permitting the production of perforations during the operation' of a separate controlling machine; to

rovide a multiple control device for perorating machines whereby any one of a number of controls can be employed to produce respectively predetermined operations of the perforating machine; to provide a settable control for perforating machines whereby any one of a number of different group perforations can be made in a record card or cards; to provide a selecting bar for a per forating machine having a plurality of universal controls differing in character; to provide a control means of multiple positions arranged to be set to cause a predetermined perforating operation; and to provide other improvements as will hereinafter appear.

In the accompanying drawings, Fig. 1 represents a side elevation of a typewriter equipped with one form of the present in- Ventron; Fig. 2 represents a detail of the same showing the selecting bar of the present invention in front elevation; Fig. 3 is a diagram of the control circuits; and Fig. 4 is a diagram representing any one of the key control circuits. j

Referring to the drawings, attention is first directed to Fig. 4 in order that a clear understanding of the resulting function of the present invention may be had. In the present embodiment of the invention it is shown as arranged to control selectivel the energizationa of a plurality of solenoi s 10, one of which is in each controlcircuit and for the purpose of simpliiied description,

15, in order to prevent movement of a punch 16S/when the punch frame 17 and card registering plate 18 are moved upward relative to the punch 16. It may be said at this point, that this punch mechanism is one unit of a complete card punching mechanism wherein latches, such as 14, are selectively set so that the respective punches, controlled by the set latches, function to perforate the card, while those punches which are not held by said latches are free to move with the card and do not perforate it. More detailed information as to the punch structure may be had by reference to United States Letters Patent No. 1,305,557, whih mechanism has here been selected to represent the operation of the present invention.

The solenoid 10 is includedv in a circuit having a conductor 20 connected to a contactor 21 which is oppositely disposed with respect toa contact 22 connected by a conductor 213 to a contact 24.' The contactor 21 is arranged to be operated by the ordinary actuation of a key 25 of a typewriter 26, this key 25, as here shown, being one of the number keys of the typewriter. Oppositelydisposed with respect to the contact 24 is a contactor 27 connected to the common return conductor 28 of the circuit which includes a rheostat 30, a switch 31 and a generator 32.

The foregoing circuit may be taken as any one of the typewriter number key control circuits of Fig. 3 and since the contactor 27 is in the common return of all circuits, the operation of any circuit typewriter number key when this contactor 27 is closed, will cause the circuit corresponding to that typewriter number vkey to close and thus set the punch corresponding to the actuated key 25. For example, if the number 8 key of the typewriter is actuated, its' circuit will be closed and punch number 8 in the unch mechanism will be set to punch ahole mthe movement of one face of a selecting bar 34.

In the present instance, this bar is squarein cross section so that it may be provided with fourcontrolsurfaces though it will be understood the invention is not limited to this number of control surfaces but comprehends the use of a bar of polygonal section any face of which may be used for control purposes.

In Figs. l and 4, the bar is shown as provided with four control surfaces while in Fig. 2 it is shown as provided with two control surfaces. One of the surfaces may be high or low throughout the whole length of the bar as is obvious. As here shown this selecting bar 34 is mounted upon the carriage 35 of the typewriter while the contactor 27 and its associated parts are carried by the fixed frame 36 of the typewriter. It will thus be seen, as the typewriter carriage moves step by step across the machine, that the selectingbar 34 will likewise move beneath the contact roller 33.

In order to make automatic selection of the columnar typewritten matter columns `to be perforated on the card, the control faces of the bar 34 are provided with dwells 37 formed by recesses 38 cut respectively transversely in the faces of the bar`l34. The arrangement of the bar with respect to the contact roller 33 is such that when a dwell 37 engages the roller 33, it will move the contactor 27 against the contact 24, but when a recess 38 arrives opposite to the roller 33 no movement of the contactor 27 will take place because the depth of the recess receives the roller 33 34 and having such dwells of predetermined without imparting movement to it. Therefore, by arranging the dwells 37 at predetermined locations along the selecting bar length, one column of the card or several successive columns of the card are automatically selected for punching. Since different card groups may require vdifferent column punching from other card groups, theibar 34 has each face provided with differently arranged dwells and in this way a predetermined card punching is made for each group of cards. 40 for turning movement and has a hand wheel 41 by which it can be given the necessary partial rotation to bring a face into operative osition and in which position the bar 34 is firmly held by a detent spring 42.v

In order to lessen trouble incident to sparking at the contacts, a condenser 43, of suitable capacity, bridges the circuit at the required location.

Additional contactor operated circuit The bar 34 is mounted in brackets closers are provided, one, 44, being arranged to be operated by the carriage return manual control key45 of the machine; another 46 for skip purposes; another 47 for manual controlof the punch and typewriter carriage return and being arranged in parallel with the circuit closer 48 which serves to bring about the automatic return of the punch carriage. The typewriter space bar is shown by reference 50.

In Fig. 3, the circuit closers including the contactors 27 are numbered to correspond to the number positions of a card column and while but two keys 25 are shown in this diagram, it is to be understood' that there is a key 25 for each closer and the omission is made only for simplification of the drawings.

The operation is as follows :n The selecting bar 34 is rst set to bring the face, which 'has dwells 37 arranged to produce acard perforation arrangement corresponding to the group data to be listed or recorded by the separate controlling machine, in this instance During its travel the successive dwells 37 shift the roller 33 to close the contactor 27, which is common to all of the circuits, so that the operation of any'number key 25 will close the circuit of the key operated and thus make a set-up of the punch controlled by that circuit. When a' recess 38 is opposite the roller 33, thecommon circuit closer Vremains open and hence the operation of any number key will not cause any punch set-up to be made. In this way, the typewriter fimctions in the ordinary way making a record ofl the data typed, and only that part ofthe typewritten matter is perforated which has .een previously selected by the choice of selectlng bar face. While the present arrangement embodies a punch set-up from number keys of the typewriter it is obvious that sumlar control can be had by arranging for contact operation by letter keys or any other characters..

While the foregoing description has referred specifically to a typewriter, it is to be understood that suchreference is merely illustrative of one application of the invention because broadly the invention is applicable to many other machines and where in the claims the term recording machine occurs, it iste be taken as generic, meaning a typewriter, a tabulating machine, a bookkeeping machine, or any other machineforating mechanism through the medium of the present invention. v
